The category Nuts are fruits from a tree (or shrub) consisting of a hard or tough nutshell protecting a kernel which is usually edible. We use the common approach to nuts and not the botanical definitions.

The products founder under Nuts are only minimally processed and have few added ingredients (salt, oil).

15.349 products are categorised under Nuts on 26 December 2024.

The super (parent) categories of Nuts is:

Usage-based super categories

Salted and grilled almonds can be seen as salty snacks.

Sub-categories

These subcategories are exclusive: a product cannot be assigned to more than one of the subcategories. This category has several subcategories:

Nutritional information

Almonds nutritional profile

The plots seem to suggest that there are two nutritional subcategories.

Almonds

  • Vipd = the interpercentile distance (V90% - V10%)
  • Vlower = V10% - Vipd
  • Vupper = V90% + Vipd

The distribution of proteins seem to suggest a subcategory (see the violin plots).

Nutrition score

The Nutrition Score suggests varies between C (146 products) and D (186 products). It is not clear whether Pine nuts should be taken into account as nuts. This would move all a score down. The median Nutriscore is Dark Green (A) if it counts as Nuts.

Median nutritional values

The two pie charts show which macronutrients make up Almonds (the missing is assumed to be water) and the origin of the energy in Almonds.

Comparing categories

There seem to be two subcategories when looking at the nutritional profiel, needs more investigation. There are a few theories:

  • Roasted almonds have lost some water (only 5% available) and thus should have higher fractions of the other nutrients;
  • Roasted almonds that have been baked in oil, should have a higher fat fraction;
  • Blanched almonds should have less fiber than almonds with the skin;

It is not yet possible to determine this as not many products have been assigned to the correct subcategories. With what we have now we cannot confirm the roasted almonds theories. The almond flakes, which are mostly blanched, seem to have 1% less fiber.

Quality checks

Categorisation errors

Sales format

The sales format might depend on the shop. All are sold by package.

Sold by weight are: - Shelled, non-blanched, unroasted almonds; - Shelled, non-blanched, roasted almonds;

Regular maintenance

Once the category has been cleaned up one can perform regular maintenance by visiting the links below and do additional repairs.

Generic errors

Hunger Game

Classify products which Robotoff has identify as category Almonds:

Extracting data

  • Nutritional values: products for which the nutritional values can be extracted from the associated image;
  • Ingredients: products for which the ingredients can be extracted from the associated image;

Superfluous categories

Only the categories that belong to the parents should be present as category. Checking the categories list might help finding wrong one.

Issues

  • peanuts count as nuts on wikipedia;
  • should we introduce tree nuts and earth nust for allergy purposes?
  • need to add chestnuts;
  • need to add coconut;
